436 ARANEIDEA. 
The name intermedia is preoccupied in this genus by Kulezynski [ Aran. Hungar. 1. 
p. 145 (1891)], and a new one is here proposed in its stead.

AGRIOGNATHA. 
Cyrtognatha, Keyserling, Verh. zool.-bot. Ges. Wien, xxxi. p. 276 (1881) (nomen preocc.). 
Agriognatha, O. P.-Cambridge, Biol. Centr.-Amer., Arachn. Aran. 1. p. 212 (1896). 
Type of Cyrtognatha, C. nigrovittata, Keys., Peru, in coll. Univ. Warsaw ; that of Agriognatha, A. bella, 
O. P.-Cambr., Costa Rica. 
The species here referred to this genus differ from Te¢ragnatha in having the lateral 
eyes in contact. In the males the apex of femur ii. has on the outer side a single 
stout spine, which is opposed by a sharp angular prominence on the patella, evidently 
used for holding the female, and femur i. (besides numerous other spines) is set with 
a row of from 4—9 spines in front. The mandibles resemble those of Pachygnatha, 
and have no basal boss on the outer side. The inner side of the protarsi i. and ii. is 
set with a single series of spiniform setz, while in the male there is also a series of 
short spines beneath. , 
I have not seen the type of the genus Cyrtognatha, Keyserl., but there is no 
reasonable doubt that Simon is correct in his identification of the characters, and his 
C. serrata, from St. Vincent, which is now before me, is congeneric with Agriognatha 
bella, O. P.-Cambr. 
The species known to me may be recognized as follows :-— 
Males. 
a. Embolus and sheath of palpal bulb strongly geniculate, the apex 
directed backwards. Bulb with a stout sharp spur on the 
outer side beneath, where the conductor and embolus spring . pachygnathoides, O. P.-Cambr. 
b. Embolus and sheath of palpal bulb merely sinuous, more 
slender. Bulb without spur on the outer side . . . . . bellu, O. P.-Cambr. 
Norse.—The female only of A. lepida has come to hand.
